The cable terminals 1A, 2A, 3A of the trunk cable 7A and the branch cable 8A are integrally connected in a detachable manner so as to be inserted into the branch connector body 4A.
This connection portion is called an “E-shaped branch connection portion” because the shape when connected is an E-shape. The power supply side trunk cable 6 is started up from the branch connection box 5A, and is connected to a substation via an overhead line. Also, the trunk cable 7A is
It will be extended to the E-shaped branch connection provided at the point B between the next station. The branch cable 8A is connected to the premises of Station A via a transformer or the like. The connection is similarly made at the connection point between the point B and the station C.

In such a cable line, for example, when construction is performed at the station C, the power supply side main cable 6 is disconnected from the power supply, and then the power supply side main cable 6 for safety.
At the point B, the cable terminal 2B of the trunk cable 7B is detached from the branch connector body 4B before the work is performed. By doing so, even if the power-side trunk cable 6 is erroneously connected to the power source during construction, the conductor of the power-side trunk cable 6 is grounded and the trunk cable 7B is disconnected. As the safety is doubled, the construction at Station C can be performed safely. In the case of construction at C station, it is most desirable to perform grounding at the branch connection part of C station. However, since there is no place where conductors can be exposed at the branch connection part, grounding cannot be performed at that place. Is the current situation.

SUMMARY OF THE INVENTION From such a current situation,
Since the point where the power-side trunk cable 6 is disconnected from the power source and the conductor ground point of the power-side trunk cable 6 are far away from the construction site, some misunderstandings suggest that the construction has been completed. It can happen that it is thrown in. In addition, point B is far away from station C, so it is troublesome to go to point B and remove the trunk cable 7B from the branch connection body 4B when performing the work at station C. There is no small risk of starting to do so. Under such circumstances, there is a problem that an electric shock accident may occur during construction.
